14 Claims.

This invention relates to improvements in fasteners and more particularly to fasteners of the hasp type for boxes, cases, and the like.

One of the objects of the invention is to provide a fastener of this character which is extremely simple and compact in construction, reliable and effective in operation, attractive in appearance, susceptible of economical manufacture, and one which may be readily applied to a box, case or similar article.

Another object of the invention is to provide in a hasp-type fastener a resilient mount for the hasp and to so organize and relate the parts that a, camming action is obtained upon movement of the hasp into closed position, tensioning the parts and avoiding accidental displacement.

Other objects and advantages reside in certain novel features of construction, arrangement and combination of parts which will be hereinafter more fully described and particularly pointed out in the appended claims, reference being had to the accompanying drawings forming a part of the specication, and in which:

Figure 1 is a front elevation of one form of the invention shown operatively applied to the hinged sections of a box, case or the like;

Figure 2 is a cross section taken on the line I-II of Fig. l;

Figure 2a is a cross section taken on the line IIa-IIa of Figure 1; n

Figure 6 is a cross section taken on the line Vl-VI of Figure 5;

Figure 7 is a front elevation of a, further modication;

Figure 8 is a cross section taken on the line VIII-VIII of Figure '7;

Figure 9 is a front elevation of a still further modification;

Figure 10 is a cross section taken on the line X-X of Figure 9; and

Figure 11 is a cross section taken on the line XI--XI of Figure 9. Y

Referring iirst to the form of the invention shown in Figures 1, 2 and 2a, the fastener com l prises a hinge plate I6 secured by any suitable means Il to one of the hinged sections I8 of a box, case or the like. The edge of the plate I6 adjacent the meeting edges of the two sections of the box is provided with Widely spaced barrels I9 and 20 to receive and support a resilient pin 23, The hasp designated generally at 29 is pivotally mounted upon pin 23, the upper edge of the hasp being rolled to provide a barrel 30 through which the pin extends. Adjacent the inner ends of the barrels I9 and 20 of the hinge plate the metal of the latter is rolled forwardly and downwardly to provide the aprons 2| and 22 which serve the dual function of centering the hasp on the pin 23 and concealing and obstructing access to those portions of the pin which extend between the barrel 3U of the hasp and the adjacent inner ends of barrels I9 and 20. The keeper plate of the Y fastener bears reference character 24 and is applied by any suitable means 25 to the other section 26 of the box or case adjacent the hinge plate I6. This plate 24 is provided with a keeper 2l shown in the drawings in the form of a hollow boss struck outwardly from the plate 24. The hasp is provided with an opening 32 adapted to engage over the keeper 2l when the .hasp is in closed position. The lower edge portion of the hasp 29 is curved forwardly as shown to facilitate gripping by the fingers inV moving the hasp in closing and opening.

The parts are so organized and related as to insure a camming action upon engagement of the lower edge of the hasp opening 32 with the keeper 2l as the hasp is moved into closed position, placing the hasp under tension and causing resilient yielding of the unsupported portion of the pin 23 upon which Ythe hasp is pivotally mounted. This action and relationship of the parts in the form of invention, shown in Figures 1, 2 and 2a, results in a frictional gripping or binding of the lower edge of the hasp opening 32 with the underpart of the keeper 2l insuring positiveness in the fastening and avoiding accidental displacement.

Referring to the modification shown in Figures 3 and 4, the keeper 36 is in the form of an open ended boss, the lower edge 31 of which is slightly reentrant. In all other respects the construction shown in this modiiication is substantially the same as that shown in the form first described. In this form of the invention the parts are also organized and related so as to provide for the tensioning of the hasp and the resilient yielding of the pin upon movement of the hasp into closed position, the closing of the hasp rst resulting in a camming action as the loweredge of the hasp opening 38 passes `over the forward rounded tip of the keeper 36 in which the hasp is tensioned and the pin is flexed, and then upon` movement vof the hasp into nal closed position a snap action is obtained as the hasp opening lower edge passes over the forward rounded end of the keeper and engages under the reentrant or upwardly inclined lower edge 31 of the keeper. In the nal position of the hasp in this form of the invention it will be noted that the tension of the hasp and flexure of the pin are released and the parts are in repose with the edge of the hasp opening positioned rearwardly of the forward tip of the keeper and slightly above the horizontal plane thereof as permitted by the upward angling of the lower edge 31 of the keeper.

In the form of the invention shown in Figures 5 and 6, two keepers in the form of forwardly extending lugs 43 are provided adjacent the upper edge of the keeper plate, and the hasp 29 instead of being provided with a keeper-receiving opening, as in the other forms previously described, is provided with shoulders 44 whichlengage under the keepers 43 in the fastening position of the hasp. The keepers in this form of the invention are also provided with rounded forward tips and reentrant or upwardly inclined edges so that substantially the same camming and snap action results when the hasp is moved into final closed position as previously described in connection with the construction shown in Figures 3 and 4 Y In the construction shown in Figures 7 and 8, the keepers V41 and 48 are formed by rolling the metal ofthe keeper plate forwardly, upwardly and rearwardly to provide a forward curved edge 49 and to provide the camming action as the shoulders 44 of the hasp ride over them in moving the hasp to closed position. In this modification, also, the lower surface of the keepers 4l and 48 are re entrant or angled slightly lupwardly so as to provide vfor the release of the hasp tension and pin flexure as the hasp is moved into nal position. It will also be noted that by reason of the formation of the keepers 41 and 48 4in this form of the invention through rol-ling of the metal as described, resiliency is provided in the keepers themselves in addition to that afforded by the pin 23. The keepers where formed as shown and described in this form of the invention may, depending upon convenience of manufacture, extend throughout the upper edges of the keeper `plate as shown at the left in Figure 7 or but partially throughout such lengthasshown at the right in said figure.

In the construction shown in themodiiication of Figures 9, 10 and 1'1, 5|- designates a forwardly extending flange integral with the hinge plate, i5. This ange overlies the barrel 30 of the hasp V29 and the barrel 38 is provided with a longitudinal eccentric rib 5 1- whi-h engages theundersurface rof the flange 5l to provide a. camming action which holds the hasp either in closed position, as shown in full lines in Figure 11', or in open position, as shown in dotted lines in said figure. The hasp is provided with inturned lugs or ngers 56 which engage, when the hasp is closed, in openings 53 provided in the keeper plate 24. The upper edges of the openings 53 are provided with forward flanges or keepers 54 which Y limit the Vinward closing movement ofthe hasp andprevent separation of the box sections when the hasp is inclosed position. The formation of theflange 5| in the `ming action which results between lthe -rib yta-l and the lilange 5l as thehasp is moved into closed and opened positions. It will be observed that there is no tensioning of the hasp in this form of the invention. In closed position, the lugs 56 merely hook under the keepers 54. The camming action and the snap action in the closing of the hasp are imparted entirely by the coaction between the cam rib 51 and the ange 5|.

`While I have shown and vdescribed several constructions in which the invention may be advantageously embodied, it is to be understood that various other `changes and modifications may be ymade therein without departing from the spirit of the invention as defined in the appended claims.
